ROLL-GRINDER.

SPECIFICATION forming part of Letters Patent No. 391,127, dated October16, 1838.

Application filed September 22, 1887. Serial No. 250,399.

To @ZZ whom, it may concern:

Be it known that I, PATRICK F. DooLnY, a citizen of the United States,residing at Malone, in the county of Franklin and State of New York,have invented a new and useful Roll-Grinding Machine, of which thefollowing is a specification.

My invention relates to machines for grinding rolls; and it consists incertain improvements in the construction of such machines, ashereinafter described and claimed.

By my improved construction certain parts are so rendered adjustablethat a rapid operation upon several rolls in a frame in succession maybe effected without removing any of them, thus dispensing with thelaborious and expensive operation of taking the rolls from and returningthem to their places in the frame of a machine.

In the accompanying drawings, Figure 1 is a front view of myimprovedroll-grinding machine. Fig. 2 is a vertical section of one of thebrackets and connecting parts. Fig. 3 is a side View of the carriagewhich carries the grinding-wheel. Fig. 4 is a horizontal transversesection of one of the slotted standards and a portion of the bracketsecured thereto. Fig. 5 is a crosssection of the bar which is traversedby the carriage.

Like letters indicate similarparts inthe several figures.

A designates the standards which support the mechanism, said standardsbeing provided with vertical longitudinal slots in their front portions,as shown. Each of the standards carries a bracket, B, which is securedby a bolt, X, to the front of the standard. The head M ofthe bolt isprovided with a threaded aperture, through which passes a verticalelevatingscrew, L, and the bolt, extending forward through a plate, l?,placed in the. vertical slot and through the bracket, is secured by ascrew and washer, so that the bracket has a swivel connection with thestandard.

On each bracket Bis placed a base-plate, C, of astand, D, the baseplatehaving a swivel connection with the bracket by means of a stud or neck,N, fitting in a holein the bracket and held in place by a screw andwasher, as shown. The stand Dhas a sliding movement forward and backwardon the base C, which (No model.)

is provided with guides for such purpose, this movement being effectedby means of the adjusting-screw having a hand-wheel, K, and a nutconnected with the stand.

per part with an opening to receive and hold one end of a hollow planedbar, H, which is thus supported in a horizontal position in front, thesaid bar extending through the stands and being adjustably secured bysetscrews. The bar H being made of any desired length, the machine maybe adjusted laterally for grinding rolls of any length desired.

The vertical elevatingscrews L are suitably mounted in the standards Aand extending downward. Each screw passes through a threaded aperture inthe head M of a bolt, X, and by means of said screws the brackets may beadjusted in elevation to grind any roll in a frame, as desired. Thescrews L are operated by means of beveled gear-wheels U ou ashaft,V,which is provided with a hand-wheel, R, said beveled gearsengaging with similar wheels on the upper extremities of the screws.

On the bar H is placed a sliding carriage, E, the lower part of which isconstructed with an opening, through which the said bar extends, suchopening forming a bearing and the carriage being held steadily inposition on the bar. The upper part, F, of the carriage is provided withbearings for a shaft, on which is placed an emery or grinding Wheel, G,and also a pulley, T. The said part F has a sliding movement on the mainpart E, and is adjustable forward or rearward, the movement beingeffected by means of a screw provided with a hand-wheel, S, and a nut(not shown) within the carriage. During operation the carriage movesalong on the bar H, being actuated by means of a screw-shaft, I, havingbearings in the stands D, and passing through a nut, Y, which is securedto the lower part of the carriage. (See Figs. l and 3.)

The screw-shaft may be driven by powerimparted from a rotary drum abovethrough extended end of the shaft, the central pulley being fast on theshaft and the others loose. The belts may be shipped by means of a rod,(not shown,) which is provided with adjustable Each of the stands D isprovided in its upstraight and cross belts tothe pulleys J on thecollars, the said collars being set to fix the distance to be traversedby the carriage. When the carriage, being driven by the screw I, comesin contact with a collar at either end of the' The hollow bar H isprovided with a num-l ber of webs,h, crossing its interior to strengthenand render it iirm and prevent auyjarring or trembling motion of the barduring operation.

In preparing for operation, the standards A are bolted to the frame ofthe machine carrying the rolls to be dressed by means of the inner parthaving the face Q, (see Fig. 4,) and which is at right angles with frontpart, Z, the plate P being shown in the slot of the standard andsupplementary plate P against the back of the front part, Z. Thegrinding-wheel is adjusted to the roll by raising or lowering bracketsB, carrying bar H, the said bar being brought into alignment with theaxis of the roll by means of the screws with hand- WheelsK, and theshipper-rod is adjusted according to the length of surface on the rollto `be ground. The shipper-rod, or the collars thereon, may be movedduring operation, if desired, and if it is desired to adj ust the bar Hat either end in its elevation either of the gear-wheels U may be thrownout of engagement for such purpose. The depth of dress ing by thegrinding wheel is regulated by means of the screw with hand-wheel S, bywhich the wheel is moved to or from the roll.

I claim as my invention and desire to secure by Letters Patentl. Inmachines for grinding rolls, the combination of the vertical standardsA, adapted to be secured to roll-frame, the brackets B, verticallymovable on said standards, the nonrevoluble longitudinal bar H,connecting the said brackets, the traversing carriage mounted on saidbar, and the shaft journaled in said carriage and having the emery-wheeland connections to rotate the same, substantially as 5o described.

2. The combination of the vertical sta-ndr ards A, the brackets movablethereon, the vertical screws j ournaled in said standards and engagingsaid brackets, the non-revoluble bar connecting the brackets, thetraversing carriage having the grinding apparatus and mounted on saidbar, and the screw I, engag ing said Vcarriage and adapted to move thesame on the bar, substantially as described.

3. The combination of the standards havingthe vertical slots, the platesP, arranged in said slots, the brackets B, the bolts X, connecting saidbrackets to said plates and having the heads M, the vertical screws L,jour naled in the standards and engaging the heads M, the non-revolublebar H, connecting the brackets, and the traversing carriage mounted onsaid bar and having the grinding apparatus, substantially as described.

4. The combination of the standards A, the vertically-movable bar H,connected thereto,

'the carriage E, mounted on said bar and having the part F, the screw S,to move said part at right angles to the bar, the shaftjournaled in partF and having the emery-wheel and pnlley T, and the screw I, journaled inbar H and engaging the carriage to traverse the same on said bar,substantially as described.

5. The combination of the-:standards A, the vertical movable brackets B,secured thereto, the stands C, swiveled to said brackets, the screwactuated stands D, movable on said stands C, the bar H, connectingstands D, and the traversing carriage mounted on said bar and having thegrinding apparatus, substantially as described.

6. The combination of the -vertical standards A, the vertical screws L,journaled in said standards, the horizontal shaft V, the mitergearsconnecting said shaft to screws L, the

brackets B, guided on standards Aland engaged by screws L, thenon-revoluble bar H, supported on said brackets, and the travers ingcarriage on said bar and having the grinding apparatus, substantially asdescribed.
